BackgroundTo use advanced medical technologies (AMTs) correctly and safely requires both specialist knowledge and skills, and an awareness of risks and how those can be minimized. Reporting safety concerns about AMTs in home care can contribute to an improved quality of care. The extent to which a health care organization has integrated the reporting, evaluation and learning from incidents is a key element of that organization's patient safety culture.ObjectivesTo explore nurses' experiences regarding the education followed in the use of AMTs in the home setting, and their organizations' systems of reporting.DesignDescriptive cross-sectional design.Methods209 home care nurses from across the Netherlands who worked with infusion therapy, parenteral nutrition and/or morphine pumps responded to the online questionnaire between July 2018 and February 2019. The analysis of the data was mainly descriptive.ResultsEducational interventions that are most often used to learn how to use AMTs were, as an average over the three AMTs, instruction by a nurse (71%), practical training in the required skills (71%) and acquiring information to increase theoretical knowledge (69%). Considerable attention is paid to patient safety (88%) and the home setting (89%). However, a substantial proportion of the nurses (up to 29%) use AMTs even though they had not been tested on their skills. 95% of the respondents were well acquainted with the incident reporting protocol of their organization, but only 49% received structural or regular feedback on any actions taken as a result of event reporting.ConclusionsThis study revealed aspects of nurses' education that imply risk factors for patient safety. Practical training is not always given, additional or retraining is often voluntary, and the required skills are not always tested. However, the results show that nurses do have a good awareness of patient safety. Incidents are mainly discussed within the team, but less at the organizational level.
Evidence-based insertion and maintenance strategies for neonatal vascular access devices (VAD) exist to reduce the causes of VAD failure and complications in neonates. Peripheral intravenous catheter failure and complications including, infiltration, extravasation, phlebitis, dislodgement with/without removal, and infection are majorly influenced by catheter securement methods.

Background: Intravenous (IV) therapy using short peripheral IV catheters (PIVC) is commonplace with neonatal patients. However, this therapy is associated with high complication rates including the leakage of infused fluids from the vasculature into the surrounding tissues; a condition referred to as, peripheral IV infiltration/extravasation (PIVIE). Objective: The quality improvement project aimed to identify the prevalence of known risk factors for PIVIE in the neonatal intensive care unit (NICU) and explore the feasibility of using novel optical sensor technology to aid in earlier detection of PIVIE events. Methods: The plan, do, study, act (PDSA) model of quality improvement (QI) was used to provide a systematic framework to identify PIVIE risks and evaluate the potential utility of continuous PIVC monitoring using the ivWatch model 400® system. The site was provided with eight monitoring systems and consumables. Hospital staff were supported with theoretical education and bedside training about the system operations and best use practices. Results: In total 113 PIVIE's (graded II-IV) were recorded from 3476 PIVCs, representing an incidence of 3.25%. Lower birth weight and gestational age were statistically significant factors for increased risk of PIVIE (p = 0.004); all other known risk factors did not reach statistical significance. Piloting the ivWatch with 21 PIVCs using high-risk vesicant solutions over a total of 523.9 h (21.83 days) detected 11 PIVIEs (graded I-II). System sensitivity reached 100%; 11 out of 11 PIVIEs were detected by the ivWatch before clinician confirmation. Conclusions: Prevailing risk factors for PIVIE in the unit were comparable to those published. Continuous infusion site monitoring using the ivWatch suggests this technology offers the potential to detect PIVIE events earlier than relying on intermittent observation alone (i.e. the current standard of care). However, large-scale study with neonatal populations is required to ensure the technology is optimally configured to meet their needs.

MSEs have encountered limitations while pushing the limits of catheter tip sensors performance. The limitations summarized: - sensors are not immune to electrical signal noise, cross talk, and EM fields; - sensors are not immune to high magnetic fields, i.e. not suitable for MR imaging; - extending the amount of sensors on the catheter tip is limited due to cluttering of wires. A fundamentally different approach using integrated optics is chosen for developing a new generation catheter sensors. The complexity of the design and production problems represents a knowledge gap, that can be bridged in the proposed consortium. This project consists of four work packages, total duration two years, subdivided into four phases. A crucial deliverable of the project is presented at the end of phase IV (WP4), namely a demonstrator integrating pressure and temperature sensors (obtained from WP1) with a newly designed readout system. This system is modularly extendable for future catheter tip sensors. In WP1, pressure- and temperature sensors are developed using two design approaches. In WP2 the influence of downscaling an ultrasound MZI device is explored and the microfabrication process parameters are studied. An additional goal of WP2 is to find the most suitable method for measuring lactate concentration. Among the deliverables five manuscripts: manuscript 1 includes simulations and measurements of the developed pressure and temperature sensors, manuscript 2 answers the question: can a grated fiber be used for measuring pressure and temperature on a tip? Manuscript 3 answers the question: which method is most suitable for measuring lactate concentration on a tip? Manuscript 4 answers the question: does a US intensity detector fit on a catheter tip while obeying the LoR? Manuscript 5 describes the performance of the demonstrator (Phase IV), i.e. integration of T/P sensing with a modular read out system.
